Abstract

em um dispositivo de filtração de peneira rotativa (100) para fluidos de média a alta viscosidade, que compreende uma peneira rotativa (20) montada rotativamente em uma carcaça (10) com pelo menos um elemento de peneira (21) pelo qual pode passar um fluxo, a peneira rotativa (20) na área das suas superfícies de vedação (22, 23, 24) e as placas intermediárias (13, 14, 15) são juntamente produzidas ou são processadas de modo que tenham uma altura idêntica. então, uma camada de ajuste de largura de abertura de intervalo (16) é interposta entre a placa de entrada (12) e a placa intermediária (15) e/ou entre a placa de saída (11) e a placa intermediária (15). finalmente, o pacote das placas (11, 12, 13, 14, 15) via pinos roscados (17) é pré-tensionado, de modo que todas as placas (11, 12, 13) estejam firmemente juntas até uma pressão operacional máxima permitida (po). entre as superfícies de vedação (22, 23, 24) e as superfícies internas opostas de placas de entrada e de saída (11, 12) surgem aberturas de lubrificação (25, 26) com uma largura definida.in a medium to high viscosity rotary screen filtration device (100) comprising a rotary screen (20) rotatably mounted in a housing (10) with at least one screen element (21) through which a In this flow, the rotary screen (20) in the area of its sealing surfaces (22, 23, 24) and the intermediate plates (13, 14, 15) are jointly produced or processed so that they have an identical height. then, a gap opening width adjustment layer (16) is interposed between the input plate (12) and the intermediate plate (15) and / or between the output plate (11) and the intermediate plate (15). . Finally, the package of the plates (11, 12, 13, 14, 15) via threaded pins (17) is pre-tensioned so that all plates (11, 12, 13) are firmly joined to a maximum allowable operating pressure. (powder). between the sealing surfaces (22, 23, 24) and opposite internal surfaces of inlet and outlet plates (11, 12), lubrication openings (25, 26) of a defined width appear.
